Abstract
This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.
